我厂熔模铸造用塑料镀铜压型是在塑料压型的基础上发展起来的。塑料压型制造周期短、新产品试制上马快,但因散热性能不好、精度不高、取模困难,而不能适应大量生产的需要。在毛主席的“多快好省地建设社会主义”总路线的光辉指引下,为了进一步贯彻落实毛主席的“备战、备荒、为人民”的伟大战略方针,使模具生产适应战备生产的发展,我们通过反复试验,不断总结经验,终于在实践中学会并掌握了塑料镀铜制造压型的新工艺。塑料镀铜制造压型是在塑料压型的型腔内镀一层一定厚度的金属层,吸取了塑料压型制造方便和金属压型散热快、精度高的长处。现将这种新工艺的试验应用情况小结如下,供参考。
Our factory investment casting plastic copper pressure is based on the plastic pressure type developed. Plastic pressure-type manufacturing cycle is short, the trial production of new products quickly, but poor heat dissipation, accuracy is not high, the mold is difficult, but can not meet the needs of mass production. Under the glorious guidance of Chairman Mao’s general line of “building socialism with more efficiency and with less expense”, in order to further implement Chairman Mao’s great strategic guideline of “preparing for war, preparing for waste and for the people,” and to adapt the production of molds to the development of combat readiness equipment production, Through repeated experiments, continue to sum up experience, and finally learned in practice and grasp the new technology of plastic-plated copper manufacturing pressure. Plastic copper manufacturing pressure is in the plastic pressure-type cavity plated with a layer of a certain thickness of the metal layer, drawing plastic pressure-type manufacturing convenience and metal pressure-type heat dissipation, high precision advantages. Now the application of this new technology test cases are summarized below for reference.
